The present invention relates to a liquid filtration apparatus, and more particularly, in separating sludge and the like contained in various liquids into sludge and liquid, respectively, the pressurized liquid required for an object having a higher concentration of sludge than a liquid amount. As a more smooth separation / filtration, as well as continuous filtration can be made.

Filter presses, which are commonly used as treatment facilities in various processors, filter the sludge containing liquid between multiple installed filter plates by compression to filter sludge and separate / filter only the original liquid (water, oil, chemical solution). Equipment used.

1, the filter press 1 schematically illustrated in FIG. 1 contains a high concentration of sludge aggregated in a settling tank 1-1, etc. in a state in which a plurality of filter plates 2 are pressed by a hydraulic apparatus 1a. A liquid is pumped by a pump (not shown) to be supplied to the liquid injection hole 2a formed by the filter pad 3 sealed between the filter plates 2 of the filter press, which is a dehydration device. 3) the sludge remains, and only the desired pure liquid passes through the filter pad 3 and is discharged to the liquid discharge hole 2c through the groove of the uneven portion 2b formed in the filter plate 2.

As shown in Figs. 2 and 3, the filter plate 2 is formed with a filtration surface 2d having uneven portions 2b of a predetermined depth on both surfaces thereof, and a liquid containing sludge in the center of the filtration surface. The liquid injection hole (2a) that can pass through, the liquid discharge hole (2c) is formed in the same direction as the liquid injection hole (2a) in each of the four corners of the filter plate 2, the liquid discharge hole 2c penetrates through the filtration hole 2e on one side of the filtration surface 2d.
